Electronic Communications Disclosure Guidelines

9 Maintaining Site Integrity Electronic communications on the Internet are not always secure. TSX recommends that an issuer establish procedures to assure maximum security of its web site and e-mail. As electronic technologies evolve, security measures also evolve. To ensure the security of its electronic communications, TSX suggests that an issuer: • review and update its security systems regularly; • be aware that it might be possible for unauthorized persons to alter the content of the site; • monitor the integrity of its web site address to make sure that the site is accessible and has not been altered. Toronto Stock Exchange Monitoring of the Internet TSX regularly monitors listed issuer web sites as well as chat rooms, newsgroups, and social media on the Internet. TSX has the capability to review alterations to listed issuer web sites and to perform random searches of the Internet to identify active discussions relating to listed issuers. However, such monitoring can never be exhaustive. Issuers are responsible for maintaining their web site and should continue to make Market Surveillance aware of significant rumours or problems relating to Internet discussions.
